Allen-Bradley 80190-440-03-R Power Supply Board for PowerFlex 7000

Product Description

The Allen-Bradley 80190-440-03-R is a dedicated internal power supply board designed for Rockwell PowerFlex 7000 medium voltage drives. It converts the auxiliary input voltage into multiple stable DC voltages to supply power to control boards, gate drive boards, signal sampling circuits and optical communication modules inside the MV drive cabinet. Built with surge suppression and isolation protection, it provides reliable power for the whole control subsystem, and it is a critical spare part for maintenance and refurbishment of legacy PowerFlex 7000 variable frequency systems.

Product Functions

• Generate multi-channel regulated DC power outputs for drive control and gate drive circuits
• Isolate and filter auxiliary power to reduce interference from high-voltage power circuits
• Integrated overvoltage, overcurrent and short-circuit protection to avoid secondary damage
• Provide power-good status signal feedback to the main controller for power monitoring
• Support stable operation under fluctuating auxiliary power supply conditions
• Standard plug-in rack structure for direct replacement inside PowerFlex 7000 cabinet

Application Scenarios

• Power plant large fans, blowers and circulating pump medium voltage drive systems
• Oil & gas, mining compressors and heavy-duty pump control equipment
• Cement, metallurgy and chemical industry medium voltage variable frequency drives
• Large industrial energy-saving and utility MV motor control systems
• Spare replacement and maintenance of existing PowerFlex 7000 drive cabinets
